My invention relates to air cleaner cases and is an improvement over thedevice described in my co-pending patent application for Dustcollectors. Serial Number 386.833, and filed August 19, 1929, and issuedas Patent No. 1,7 88,410 January 13, 1931. Certain objects of thepresent invention are to provide adjustable means for the air intake anddischarge members, adjustable means for the main or straight baflieplate, detachable claimed. These objects are accomplished by devicesillustrated in the accompanying drawings; wherein Figure 1 is a view inside elevation of the forward portion of a motor truck showing my deviceinstalled therein;

Figure 2 is a detail view in perspective of the device;

Figure 3 is a view in longitudinal vertical section of the same;

Figure 4 is a view in horizontal section taken substantially on a brokenline 4, 4 of Fig. 3; and

Figure 5 is a view in perspective showing fragmentary portions of theadjustable baflle plate.

Referring to the drawings throughout which like reference numeralsdesignate like parts, the numerals 5 and 6 indicate the twocomplementary halves of the main cleaner casing that are securedtogether by means of four long bolts 7. As shown in Figs. 2 and 4:, thethreaded ends of said bolts project at some length exteriorly of thecasing and may be used for securing the device to brackets or otherwisefastening same to the motor or other convenient place as will beunderstood.

The numeral 8 designates the top or lid which may be secured in place onthe upper flanged edges of the main casing by means of a pair of hookedlugs 9 and a pair of stud bolts 10. The intake member 11 for said top isheld in place by a bolt 12 that is centrally threaded into a spidermember 13 provided for the intake opening and when said bolt is loosenedthe intake member may be adjustably revolved to any desired position onits annular seat. The outlet or discharge member 14 is similarly mountedby means of a bolt 15 threaded into a spider 16 and may likewise beadjustably revolved around its opening.

Complementary halves of lugs 17 are formed on the flanged abutting endedges of the two main casing halves 5 and 6 which provide mountings forhooked bolts 18 when the casing is assembled. The hooked ends of saidbolts engage under the flanges of a bottom pan 19 whereby said pan maybe readily removed for cleaning. A plurality of spaced baflleprojections 20 is provided for the bottom of said pan some of which maybe provided with T-heads 21. Oil is placed in said pan and these bafileprojections prevent the oil from being sucked into the motor. It will beunderstood that the oil collects the dust from the air upon coming intocontact therewith as in my former application.

A plurality of curved baflie plates 22 is mounted within the main casingand said baffles are disposed in spaced apart relation to provideconduits that are in communication with the outlet opening of thedischarge or outlet member 14 as clearly shown in Fig. 3 of thedrawings. Each of said baflies comprises a felt pad 23 held betweensheet metal plates 24. A plurality of cups 25 is pressed outwardly fromsaid plates with openings on the lower sides so they will catch the dustin its upward flow.

A straight adjustable baffle plate 26 is pivoted at 27 in the topportion of the main casing and slants forward and downward to a bolt 28.A nut 29 mounted on said bolt is swiveled between bracket lugs 30 on thelower end of said baflie. Said bafi'le plate )I'O vides an entry passage31 for the air an by turning said bolt the plate is moved back and forthwhereby the entry passage may be adjusted in conformity with the air ca-As the engine speed is increased the v0 ume of air also is increasedtherefore the increased draft causes the bafile to pull against thespring thus allowing the correct amount of air thru the cleaner at allspeeds of the engine eliminating resistance and back firing. This baffleplate likewise comprises a felt pad 23, sheet metal plates 24 and cups25 that are similar to the corresponding parts of the baffles 22 withthe exception that the cups are open on their upper sides in order tocatch the dust from the downwardly flowing air.

A plug 32 is threaded into the main casing and same may be removed forthe installation of a tube 33 in the threaded opening. Said tube isusually connected to the crankcase breather and relieves the crankcaseof gases and other foreign matter which are purified and removed inpassing through the cleaner. The vapor oil that is mixed with the gasesis deposited on the felt pads of the battles and keeps them moist sothat the dust will adhere thereto more readily.

The principal improvements in the deviceof my present applicationcomprise the adjustable means for the intake and discharge members 11and 14 respectively, the adjustable means for the baflie plate 26, thedetachable means for the bottom pan 19 together with its baflieprojections, the elimination of the inner casing of the formerapplication, and the incorporation of other de tails of construction asherein set forth.

The operationof the device was fully set tions for the pan, and bafileplates for direct-' a ing the air from the intake to the pan and thencethrough the outlet.

2. An air cleaner case comprising a main casing, a detachable top forthe casing, an air intake and an air outlet member for said top, abottom pan detachably secured to the casing and having oil therein, aplurality of upstanding spaced apart baflie projections for the pan somehaving T-heads, a plurality of curved baffle plates spaced to formconduits communicating with the air outlet, a straight baffle platearranged to form a passage chamber for the intake, and pivotal adustingmeans for said straight baflle.

3. An air cleaner case comprising a casing consisting of complementaryhalves detachably secured together, a detachable top, an air intake andan air outlet member for the top, adjustable means for said intake andoutlet members, a bottom'pan having oil therein, bafile projections forthe pan, means for detachably securing the pan to the easing, aplurality of curved bafiie plates spaced to form conduits for the airoutlet, a straight baflle plate adapted to direct air from the intaketo-the bottom pan, adjustable means for said straight baflie, saidcurved and straight baflles each comprising a felt pad secured betweenmetal plates, projecting pockets for said metal plates, the pockets forthe curved baffles being open on their lower sides, and the pockets forthe straight baffle open on their up er sides.

In testimony w ereof I aflix my signature.

forth in my former patent application and no description in detail ishere considered necessary except'to state thatthe air is suckeddownwardly through the intake 11 and passage 31 into the pan 19; Uponstriking the oil in the bottom of said pan the dust is partly removedand the air then rebounds upwardly through the conduits between thebaffle plates 22. The projecting pockets or cups 25 catch the airmomentarily and the dust therein adheres to'the oil saturated felt pads.

Having thus described my invention, it being understood that minorchanges may be resorted to in its construction Without departing fromits scope and spirit, what I claim and desire to secure by LettersPatent of the United States is 1. An air cleaner case comprising acasing consisting of complementary halves detachably secured together, atop, an air intake member for the top, an air outlet member for saidtop, means for revolubly adjusting said intake and outlet members, abottom pan having oil therein, detachable means for securing said pan tothe casing, bafiie'projec-
